Introduction: The enteric nervous system (ENS) in the wall of the gastrointestinal tract is complex and comprises many neurons, which are differentiated in terms of structure, function and neurochemistry. Neuregulin 1 (NRG 1) is one of the neuronal factors synthesised in the ENS about the distribution and functions of which relatively little is known. The present study is the first description of the distribution of NRG 1 in the ENS in various segments of the porcine small intestine.

Robot-assisted pancreaticobiliary junction resection is a surgical technique employed to treat benign duodenal tumors. The procedure involves several key steps: making a longitudinal incision in the duodenum, excising the tumor at the pancreaticobiliary junction, inserting a biliary stent, connecting the biliary and duodenal mucosa, and suturing the duodenal incision during phase I. The robotic system enhances visibility, facilitates precise operations, minimizes duodenal traction injuries to the duodenum and surgical trauma, ensures accurate suture and fixation of bile duct stents, connects the bile duct and duodenal mucosa and reduces postoperative recovery time.

BACKGROUND Brunneromas are among the rarest benign tumors of the upper gastrointestinal tract. They arise from the Brunner's glands and patients have a good prognosis if treated timely and radically. Because symptoms are rare, their diagnosis can be challenging, especially regarding the smaller ones.

The aim of this study is to describe the ultrasonographic features of feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) before histological diagnosis and during follow-up after surgical excision and/or medical treatment. This multicentric retrospective case series study includes medical records of cats diagnosed histologically, which had an ultrasound before diagnosis and a minimum of one follow-up ultrasound at least 4 weeks after treatment. Thirty cats were included in the study.

Mesenteric cysts are rare intra-abdominal masses which can occur at any point in the gastrointestinal tract from the duodenum to the rectum. These cysts may remain asymptomatic or may present with an abdominal mass, abdominal pain, or fever. Management may be conservative, percutaneous, or surgical excision.
